Necrotizing myopathy statin

More recently, an immune-mediated necrotizing myopathy has been found to be associated with statin use which in most cases requires treatment with immunosuppressants. Objective To perform a systematic review on published case reports and case series of statin-associated autoimmune myopathy. Methods A comprehensive search of PUBMED, EMBASE, Cochrane library and Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the treatment. Among autoimmune manifestations associated with statins, there is immune-mediated necrotizing myopathy (IMNM). 2020-01-08 · Statin-induced immune-mediated necrotizing myopathy (IMNM) was initially described in patients on statin therapy who, despite statin discontinuation, developed a persistent myopathy, responsive only to immunosuppression [ 1 ]. Statin Induced Necrotizing Myopathy Michael Wongchawart, M.D., and Roswell Quinn, M.D., Ph.D.

More recently, an immune-mediated necrotizing myopathy has been found to be associated with statin use which in most cases requires treatment with immunosuppressants.

Phenotype Standardization for Statin-Induced Myotoxicity

Statin-associated myopathy comprises of a spectrum of conditions ranging from benign myalgias to statin-induced immune-mediated necrotizing myopathy. Statin-induced immune-mediated necrotizing myopathy is an autoimmune condition wherein there is a destruction of normal skeletal muscular architecture that can be severely debilitating if not recognized promptly. e severe symmetrical proximal myopathy, associated with a markedly elevated creatine kinase level.

However, a rare and severe form of statin-induced necrotizing autoimmune myopathy (SINAM) has recently been described and can lead to debilitating weakness, often requiring immunosuppressive therapy. Necrotizing myopathy is a newly defined form of idiopathic inflammatory myopathy, or myositis. Patients with necrotizing myopathy have muscle biopsies that show much less inflammation in the muscle tissue than polymyositis patients, but they have increased evidence of muscle cell death, or necrosis. The association of statins with necrotizing myopathy is strengthened by the discovery that the serum of some of these patients contains an anti-HMGCR antibody. This suggests that statins can cause or unmask an immune mediated myopathy.

The review aims to define this heterogeneous entity and summarize the salient clinical, laboratory, and muscle biopsy findings, in order to facilitate the diagnosis and treatment of this condition. Recent findings Statin Statin-associated IMNM is a recently described entity based on the development of autoantibodies against the enzyme HMGCR, and leads to a necrotizing myopathy requiring immunosuppressive therapy.

Statin-induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare yet devastating complication of statin therapy that can occur at any time after initiation. It should be considered Statins and Immune-Mediated Necrotizing Myopathy Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the treatment.

The most common adverse effects include weakness and myalgias.

Results of a muscle biopsy showed necrotizing myopathy with minimal inflammatory cell infiltrate and increased major histocompatibility class I antigen expression in muscle fibers. Statin-induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare yet devastating complication of statin therapy that can occur at any time after initiation. It should be considered Statins and Immune-Mediated Necrotizing Myopathy Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the treatment.

No evidence of statin use, active malignancy, or connective tissue disease was found. He was treated with high-dose corticosteroids and a short course of intravenous immunoglobulin with very mild improvement in symptoms. 2018-11-01 · This study aimed to clarify the phenotypes and therapeutic responses of statin-naïve anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibody-mediated necrotizing myopathy. Anti-HMGCR antibodies were tested with ELISA methodology in the sera sample of 98 patients meeting the idiopathic inflammatory myopathy criteria and with negative anti-signal recognition particle (SRP) antibody.

Statin-induced necrotizing autoimmune myopathy Exposure to statins prior to onset was significantly higher in patients with necrotizing myopathy (82%) as compared to those with dermatomyositis (18%), polymyositis (24%), and inclusion-body myositis (38%) seen in the same time period. The lack of improvement following discontinuation of statins, the need for immunosuppressive therapy, and Necrotizing autoimmune myopathy (NAM) is a severe adverse effect of statins. We report a 66-year-old Caucasian female who had progressive proximal muscle weakness after treatment with statins. Results of a muscle biopsy showed necrotizing myopathy with minimal inflammatory cell infiltrate and increased major histocompatibility class I antigen expression in muscle fibers. Statin-induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare yet devastating complication of statin therapy that can occur at any time after initiation. It should be considered Statins and Immune-Mediated Necrotizing Myopathy Statins are a well-recognized cause of a variety of skeletal myopathic effects, which generally resolve when discontinuing the treatment.

Patients who continue to have elevated muscle enzymes or weakness should undergo further testing with electromyography, magnetic resonance imaging, and muscle biopsy. The utilization of this combinatorial immunoassay provides accuracy and speed in diagnosis of necrotizing autoimmune myopathy (NAM). Early diagnosis facilitates better prognosis through initiation of aggressive immune treatments, typically requiring more than 1 agent, and discontinuation of statin medications.
